Duplex Steel Seamless Pipe Fittings

Kencotube is one of the pioneer manufacturer & dealer of high quality Duplex Steel Butt Weld Fittings, where the high mechanical strength of duplex grades is a result of the duplex microstructure and the alloying with nitrogen. Typical applications of Duplex Steel Butt Weld Pipe Fittings are storage tanks, bridges, water heaters and reinforcement bars. Duplex Steel Pipe Fittings is to some extent more problematic to machine than SS 300 series, where superior cutting forces are needed and more rapid instrument wear is distinctive. Duplex Steel Elbow Pipe Fittings will often perform well in environments which cause premature failure of austenitic grades. Duplex Steel Long Radius Elbow Pipe Fittings has better resistance to sea water then Grade 316, which is further a nitrogen enhanced stainless steel that was developed to combat common corrosion problems encountered with the 300 series stainless steels.

Although Duplex Steel Tee Pipe Fittings has excellent high temp oxidation resistance, it experiences from embrittlement if apprehended for even smaller times at temp more than 300 Degree C. If embrittled, Duplex Steel Reducer Pipe Fittings can only be rectified by a full solution annealing treatment, which are almost never used above 300 Degree C. The high strength of Duplex Steel Pipe End Caps Fittings gives opportunities for reducing both weight and cost as a thinner material can be used, whereas low nickel content of these duplex steel makes them price stable. Duplex Steel Reducing Tee Pipe Fittings cannot be hardened by thermal treatment, but does work harden.
